Hello,
Is There A Way To:
Lets Say The Album Artist Is: The Beatles
Is There A Way To Change The Entire Artist Column To Say The Beatles In One Move?
Normally I Have To Go Line By Line To Change Redundant Information?

Well, that's a main feature of MP3Tag.
Just mark all the relevant files in the list view, write "Beatles" in the tag-panel to the Artist field and save.
If theee is already "Beatles" in one of your artist-tags you can choose it from a list and save.
